python学习笔记（win32print API介绍）
最近博主在研究用python控制打印机
这里整理下win32print的API介绍，官网地址http://timgolden.me.uk/pywin32-docs/win32print.html
OpenPrinter 打开指定的打印机，并获取打印机的句柄
GetPrinter 取得与指定打印机有关的信息
SetPrinter 对一台打印机的状态进行控制
ClosePrinter 关闭一个打开的打印机对象
AddPrinterConnection 连接指定的打印机
DeletePrinterConnection 删除与指定打印机的连接
EnumPrinters 枚举系统中安装的打印机
GetDefaultPrinter 取得默认打印机名称 <type 'str'>
GetDefaultPrinterW 取得默认打印机名称 <type 'unicode'>
SetDefaultPrinter 对一台打印机名称 <type 'str'> 设置成默认打印机
SetDefaultPrinterW 对一台打印机名称 <type 'unicode'> 设置成默认打印机
StartDocPrinter 在后台打印的级别启动一个新文档
EndDocPrinter 在后台打印程序的级别指定一个文档的结束
AbortPrinter 删除与一台打印机关联在一起的缓冲文件
StartPagePrinter 在打印作业中指定一个新页的开始
EndPagePrinter 指定一个页在打印作业中的结尾
StartDoc 开始一个打印作业
EndDoc 结束一个成功的打印作业
AbortDoc 取消一份文档的打印
StartPage 打印一个新页前要先调用这个函数
EndPage 用这个函数完成一个页面的打印，并准备设备场景，以便打印下一个页
WritePrinter 将发送目录中的数据写入打印机
EnumJobs 枚举打印队列中的作业
GetJob 获取与指定作业有关的信息
SetJob 对一个打印作业的状态进行控制
DocumentProperties 打印机配置控制函数
EnumPrintProcessors 枚举系统中可用的打印处理器
EnumPrintProcessorDatatypes 枚举由一个打印处理器支持的数据类型
EnumPrinterDrivers 枚举指定系统中已安装的打印机驱动程序
EnumForms 枚举一台打印机可用的表单
AddForm 为打印机的表单列表添加一个新表单
DeleteForm 从打印机可用表单列表中删除一个表单
GetForm 取得与指定表单有关的信息
SetForm 为指定的表单设置信息
AddJob 用于获取一个有效的路径名，以便用它为作业创建一个后台打印文件。它也会为作业分配一个作业编号
ScheduleJob 提交一个要打印的作业
DeviceCapabilities 利用这个函数可获得与一个设备的能力有关的信息
GetDeviceCaps 获取指定设备的参数设置
EnumMonitors 枚举可用的打印监视器
EnumPorts 枚举一个系统可用的端口
GetPrintProcessorDirectory 判断指定系统中包含了打印机处理器驱动程序及文件的目录
GetPrinterDriverDirectory 判断指定系统中包含了打印机驱动程序的目录是什么
AddPrinter 在系统中添加一台新打印机
DeletePrinter 将指定的打印机标志为从系统中删除
DeletePrinterDriver 从系统删除一个打印机驱动程序
DeletePrinterDriverEx 从系统删除一个打印机驱动程序和相关的文件
FlushPrinter 更新打印机，清楚错误状态的打印机
